settling properties Lower CAPEX and OPEX Lower energy consumption Compact Easy to operate Sustainable © DHV, all rights reserved Confidential © RoyalHaskoningDHV, all rights reserved 26 BNR in activates sludge requires many compartments and circulation flows Aerobic Granular Biomass Activated Sludge Aerobic Granules Excellent settling properties Pure biomass No support media High MLSS levels (up to 15 g/L) Reliable and stable operation No bulking sludge © DHV, all rights reserved Confidential © RoyalHaskoningDHV, all rights reserved 31 © DHV, all rights reserved Confidential © RoyalHaskoningDHV, all rights reserved 33 2 Principle of Nereda® Oxygen gradient in granule Nereda® process cycle simultaneous COD, P and N-removal Simple one-tank concept Heterotrophic organisms Anaerobic zone: • Nitrate reduction to nitrogen gas • Phosphate removal COD + NOx + PO43- No clarifiers No moving decanter N2 + CO2 + H2O + poly-P No mixers Aerobic zone: • Biological oxidation • Ammonium oxidation to nitrate COD + O2 Ammonium oxidising organisms oygen NH4 + O2 Extensive biological COD, N- and P-removal CO2 + H2O Low energy consumption NOx Easy operation depth in granule ©
